[https://www.uniprot.org/uniprot/NCAP_SINV NCAP_SINV] Encapsidates the genome protecting it from nucleases (Probable). The encapsidated genomic RNA is termed the nucleocapsid (NC) and serves as template for transcription and replication (Probable). The nucleocapsid has a left-handed helical structure (By similarity). As a trimer, specifically binds and acts as a chaperone to unwind the panhandle structure formed by the viral RNA (vRNA) termini (PubMed:15650206, PubMed:15254200, PubMed:21378500, PubMed:16971445, PubMed:25062117, PubMed:16775315). Involved in the transcription and replication initiation of vRNA by mediating primer annealing (PubMed:20164193). Plays a role in cap snatching by sequestering capped RNAs in P bodies for use by the viral RdRp during transcription initiation (PubMed:19047634). Substitutes for the cellular cap-binding complex (eIF4F) to preferentially facilitate the translation of capped mRNAs (PubMed:18971945, PubMed:25062117). Initiates the translation by specifically binding to the cap and 40S ribosomal subunit (PubMed:20844026, PubMed:20164193, PubMed:25062117). Prevents the viral glycoprotein N (Gn) from autophagy-dependent breakdown maybe by blocking autophagosome formation (By similarity). Inhibits host EIF2AK2/PKR dimerization to prevent PKR-induced translational shutdown in cells and thus the activation of the antiviral state (By similarity). Also displays sequence-unspecific DNA endonuclease activity (PubMed:27261891).[UniProtKB:O36307][UniProtKB:P05133]<ref>PMID:15254200</ref> <ref>PMID:15650206</ref> <ref>PMID:16775315</ref> <ref>PMID:16971445</ref> <ref>PMID:18971945</ref> <ref>PMID:19047634</ref> <ref>PMID:20164193</ref> <ref>PMID:20844026</ref> <ref>PMID:21378500</ref> <ref>PMID:25062117</ref> <ref>PMID:27261891</ref>
